I can consistently crash Max this way.

Steps to reproduce:

1. Instantiate ANY mxj external. Even something trivial like:

import com.cycling74.max.MaxObject;
public class test extends MaxObject {
public void bang() {
post(“bang”);
}
}

2. Send the message “get 1″ to the object’s inlet. Kaboom!

#P window setfont “Sans Serif” 9.;
#P window linecount 1;
#P message 143 78 33 196617 get 1;
#P newex 143 106 101 196617 mxj playground.test;
#P connect 1 0 0 0;
#P window clipboard copycount 2;

Here is my crash log (I cut out a lot, let me know if you want the full log):
